Objective: The aim of this study was to address the first cases of TOETVA done in Brazil, by TOETVA-Bra study group, regarding safety and complications., Methods: Series of the first 93 TOETVAs cases in Brazil. All authors except LPK, AJG JOR and RPT received TOETVA training including cadaveric hands-on in Thailand or United States (Johns Hopkins Medicine) during 2017. After they came back to Brazil and started doing their first TOETVA cases in the cities of Rio de Janeiro, Sao Paulo and Chapecó they agreed to collaborate and gather data using an online spreadsheet. All patients were submitted to the technique described by Anuwong., Results: A total of 93 patients underwent TOETVA. Most patients (58.1%) were submitted to total thyroidectomy and 59.1% had benign disease. Two patients (2.2%) needed conversion to open surgery. Five patients (9.3%) developed transient hypoparathyroidism and there were 3 (2.0%) temporary recurrent laryngeal nerve palsy. There was one (0.7%) permanent unilateral palsy. Twenty patients had some sort of complication, 16.1% were minor and 5.4% were major. A total of 73 patients (78.5%) had an uneventful recovery., Conclusion: The technique is reproducible with a low complication rate. While further studies are needed to confirm equivalency, early efforts suggest that TOETVA is not inferior to traditional open thyroidectomy in appropriately selected patients.

Objective: to present the initial experience in Brazil with transoral endoscopic thyroidectomy by vestibular approach (TOETVA)., Methods: prospective study of patients undergoing TOETVA in the Department of Head and Neck Surgery of Hospital Regional do Oeste, Chapecó, Santa Catarina. Patients between 18 and 65 years of age, ASA I and II, with maximum glandular volume of 35cm3 and nodules up to 4cm were candidates for the study. Data of the patients, nodules, surgical time, complications, and length of hospital stay were recorded., Results: nine patients were operated between May 2017 and April 2018. All were women, aged 33-64 years. The size of the nodule ranged from 1cm to 4cm. Two patients had malignant neoplasia and total thyroidectomy was performed in eight cases. Seven patients were hospitalized for only one day. One patient had a minor complication on skin, but there were no lesions of the laryngeal recurrent nerves or definitive hypoparathyroidism., Conclusion: TOETVA is a safe technique for well-selected patients, with favorable conditions and special concern for aesthetic results.
